<span>Diffusion is a net movement of particles through a barrier driven by a concentration gradient. In diffusion, particles move from an area of higher concentration to the area of lower concentration in order to balance concentrations on the both sides of the barrier. For example, when you put a teabag into a hot water, concentration of tea particles in the hot water is much lower than in a teabag and the particles of tea will diffuse into water.</span>
<span> The Reactants are Zinc (Zn) and Sulfur (S).
The Product is Zinc Sulfide (ZnS).
All of them are solids.
The combined masses of the reactants must be 14 grams, too. Later in
Chemistry you'll learn that's not really true, but it is for now.
Hope This Helps:)
